A new cooling system using ammonia and water solution has been developed for small spaces. It can be powered by renewable energy sources and uses micro-channels for better efficiency. The system includes an absorber, condenser, generator, and evaporator with unique designs. The absorber absorbs ammonia vapor in the liquid flowing through micro-channels, with fins on the outside for better cooling. The researchers calculated the system's performance and designed the heat and mass transfer components. Experimental results show promising outcomes for cooling small spaces efficiently.
